Mercury Emissions Articles

Many pollutants such as CO2, NOx and SO2 have been monitored continuously already for decades. In the last years the awareness for the need to measure mercury has also grown, and continuous mercury monitoring is becoming more and more relevant. Especially industries burning coal, oil or waste, share the responsibility to monitor their mercury emissions. All measuring techniques need to be able to ...

In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger. Before diving ...

Gasmet Technologies (Finland) has published a new White Paper on the monitoring of mercury emissions to air from industrial processes. The Paper provides an overview of current initiatives to reduce mercury emissions and explains how continuous mercury emissions monitoring can help inform process control and the efficient operation of pollution abatement equipment, whilst also demonstrating ...

Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

Mercury contamination from the De Beers diamond mine in northern Ontario may be much higher than the company — or the provincial government — are reporting, according to a new study by the Canadian Parks and Wilderness Society’s Wildlands League. An investigation into one of world’s highest quality producing diamond mines has found failures in self-monitoring, raising ...

This document is the annual European Union (EU) emission inventory report to the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (CLRTAP) (UNECE, 1979). The report and its accompanying data constitute the official submission by the European Commission (EC) on behalf of the EU as a Party to the Executive Secretary of UNECE. The report is ...

Trace metals are a group of toxic pollutants that can cause serious damage to ecosystems and humans. To determine the distribution characteristics of aqueous trace metal contamination and identify critical pollution sources, it is necessary to develop a detailed estimation of trace metal emissions. By considering emission-related factors in each industrial sector, we estimate that the ...

Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in the environment at present. Thus, one might predict that the concentration of mercury in fish should have increased dramatically since the Industrial Revolution. Evidence in ...

Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

A suite of mechanistic atmospheric and mercury cycling/bioaccumulation models is applied to simulate atmospheric mercury deposition and mercury concentrations in the water column and fish in a mercury‐impaired freshwater lake located in the northeastern United States that receives its mercury loading primarily through deposition. Two future‐year scenarios evaluate the long‐term response of ...

High‐elevation ecosystems of the northeastern United States are vulnerable to deposition and environmental accumulation of atmospheric pollutants, yet little work has been done to assess mercury (Hg) concentrations in organisms occupying montane ecosystems. The authors present data on Hg concentrations in ground‐foraging insectivorous songbirds, a terrestrial salamander, and forest floor ...

In 2008, 2010, 2012, and 2013, MJB&A managed the production, budget and release of a collaborative report entitled Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States. The 2013 report was jointly published by Bank of America, Ceres, Entergy, Exelon, the Natural Resources Defense Council, Pacific Gas and Electric Company, Public Service ...

In August 2010, MJB&A and the Analysis Group completed a report reviewing the impact on power plant operations of proposed EPA rules to reduce emissions of sulfur dioxide, nitrogen oxides, mercury and other hazardous air pollutants. The report, “Ensuring a Clean, Modern Electric Generating Fleet while Maintaining Electric System Reliability,” involved a detailed analysis of ...

The Minamata Convention aims to protect human health and the environment from anthropogenic emissions and releases of mercury. The provisions of the Minamata Convention are examined to assess their influence on global biogeochemical cycling of mercury. Though the Convention's scope covers all major categories of atmospheric emissions, the degree to which it will affect future emissions ...

As a global pollutant, mercury can be transported over long distances and bioaccumulate. China is currently the greatest contributor to atmospheric Hg emissions and has the greatest intentional use of Hg. Mercuryin the Chinese environment is generally elevated, particularly in air and water bodies. Remote areas in China also show elevated Hg levels in air and water bodies compared with other ...

To investigate the source and process of inorganic mercury (IHg) accumulation in rice, we monitored the concentrations of IHg in tissues of rice plants (Oryza sativa L.) from four experimental plantation plots. Biweekly during the rice‐growing season, tissues of rice plants, corresponding soil, precipitation, and irrigation water samples were collected. The sampling data support the following: ...

As the year winds down, it’s a good time to take stock of climate policy in the United States. Here’s a quick round up of what happened – or didn’t happen – in 2011. The year began with big questions about what the Obama Administration and states would do to address climate change and clean energy, absent a comprehensive federal climate policy. This year’s ...

Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...

C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The ...

EPA published the highly anticipated proposed Maximum Available Control Technology (MACT) Standard for the utility sector (40 CFR 63 Subpart UUUUU). When considered together with the growing list of proposed and final rules impacting the utility sector (Transport Rule/Cross-State Rule, Coal Combustion Byproducts Rule, Cooling Water Intake Rule, Regional Haze Rule, revised National Ambient Air ...
